Generally____ or _____ stories high
____‘to____’ wide
____’ in depth
six or seven stories
35’ to 50’ wide

NLT(4/12/1901-1915) access to the cellar will be ________.
an exterior stair
New Law Tenements built from 1916-1929 have a much larger floor area than previously built NLTs. To avoid having to be fireproof construction the floor areas were broken up into _____ square feet or less.
2500
In newer NLTs(1916-29) between some apartments there are brick or fireproof partitions which effectively limit the horizontal spread of fire. However, these dividing walls only go as high as the ceiling of the top floor. This results in a very large undivided cockloft area. Fire can, and often does, spread throughout this large cockloft area.
T/F
true
In newer NLTs the Entrance to the basement is by a side or rear door at that level, accessed via an exterior stair from the first floor, or through a passageway located in the front of the building.
true
in nonfireoroof construction firewalls extend to:
before 1930
1930-1940
after 1940
before 1930 as high as the ceiling on the top floor
1930-40 underside of the roof boards

In OLTs and NLTs roof hoseline should be used only to: (choose the incorrect choice)
A. prevent fire from extending past the trench
B. to protect exposures
C. to extinguish fire that cannot be reached from below, such as fire in a cornice
D. operate briefly into ventilation holes to protect members operating on the roof
D.
Hoselines should not be operated into ventilation holes from the roof as this decreases ventilation and nullifies the action of lines operating on the top floor

A. Ladder Co confirms the fire apt
B. the IC gives permission
C. the safety of the stairway is assured
D. once the line is charged and bled
C

Which is not a correct use of the 3rd line at a MD fire?
A. up the interior stairs
B. rope stretch into a window
C. up a fire escape
D. into an exposure as ordered by the IC
A
This is especially true in Old Law Tenements because the stairway is narrow and the stretching of a third line via the interior stairs would result in congestion and inability to move any of the hoselines.
Windows should be opened ___ from the top and ____from the bottom to allow heat and smoke to vent and cool air to enter the room
2/3s from top
1/3 from bottom

[HRFPMD] The simplest type of duplex apartment is one that has all doors on the public hall entering apartments with identical floor layouts. Inside the apartment, a private stair leads up to bedroom areas. A second type of duplex apartment has doors leading from the public hall into the main level and the second level is down. This presents the same problems as a:
a. PD fire
b. standard apt fire
c. cellar fire
d. brownstone fire
c.
This presents the same problems as a cellar fire, with the added problem of bedrooms on this lower level with possible trapped occupants.
6.27.1 D
A third design type, while not strictly duplex or triplex apartments, but with similar problems for firefighters, is one where apartment entrance doors are in groups of threes in a public hall and there is only one public hall every three floors. This is called the _________ type apartment arrangement.
one is up a flight, one is on the same floor as the entrance door and one is down a flight. If the fire is on the lower level the ff techniques will be the same as cellar fires
6.27.1D
For duplex and triplex apartments engine ops will be the same as outlined for apartments in FP buildings except that when a 2nd line is needed.
t/f
true
3rd and 4th eng should be ready to operate thru a breached wall
hoseline should still be brought up from the floor below via attack stairs
6.27.1E

Doors on some floors have no letter or number designations on them, indicating that they are a second exit from an apartment. It is extremely difficult to tell which apartment they serve.
6.27.1 K
LRFPMDs Will vary in height, generally from ___ to ___ stories
3 to 7
7.2
Are LRFPMDs usually equipped with standpipe systems?
no
Because of the lower building height of these fireproof buildings and the heavy smoke conditions that usually occur in the attack stairway after the attack has begun, emphasis will generally be placed on venting the attack stair bulkhead after approval of the IC, early in the operation. This is done to relieve conditions in the attack stairway and/or public hallways.
t/f
true
When ordered, the venting of the attack stairway in LRFPMDs will be accomplished by the 1st and 2nd arriving Roof firefighter positions….IC must give permission

7.5.2
In a LRFPMD what is the preferred roof access for isolated buildings with two stairways?
stairs are remote and enclosed. enclosed evac stairway for roof access
7.5.3
In a LRFPMD what is the preferred roof access for isolated buildings with one stairway?
aerial or TL if possible. decision made by co off as to whether or not roof vent is required. No IDLH and apt door control roof ff can be ordered to the roof via int stair. If IDLH roof ff must be teamed up with another member. Apt door kept closed in either case until roof ff is on the roof. He will remain there with bulkhead door closed. IC can order it open. He will remain on the roof until the fire is under control and int stair is safe
7.5.4 & 7.7.3 note
Some LRFPMDs are built with very long public hallways. These buildings should be identified in the CIDS program, as they create additional operational considerations. In these buildings, the search rope should be brought as part of the tool assignment.
t/f
true
7.5.5
However, if a LRFPMD has long hallways, that is, any apartment door is more than____from any stairway on that floor, then the additional GPM available from 2½” hose may be needed and 2½” hose should be hand stretched from the pumper.
50 feet
7.6.2
In buildings with two stairways, once the attack stair has been selected, all operations are to proceed from this stairway in order to ensure the evacuation stairway is maintained clear of smoke. What is the exception to this rule?
The only exception to this procedure is when the Roof Firefighters use the evacuation stairway to reach the roof.
The 1st to arrive truck at a LRFPMD will proceed to the fire floor and notify the IC if the stairs are open or enclosed. When there are two stairways, notify the IC and the engine officer of the attack stairway. This transmission is also important to the roof firefighter since it will determine his/her route to the roof, e.g., evacuation stairs. Also, notify the IC and engine officer of the heat and smoke conditions found in the stairs or public hallways. Locate and force entry into the fire apartment if the door has not been left open. If conditions allow, enter the apartment to search. Search team must be prepared to exit quickly and control the door under all circumstances. Do not chock the door open until_____________________.
